Ib sab saum toj no, qhov twg yog cov hlab ntshav qis qis nyob tom qab?
Cov posterior nqis ntshav (PDA) kuj tseem hu ua tom qab interventricular cov leeg vim nws khiav raws tom qab interventricular sulcus mus rau apex ntawm lub plawv. Nws nyob ntawm apex qhov uas nws ntsib sab laug sab xub ntiag nqis ntshav uas tab tom taug kev ua ntej ntawm lub plawv.
